Perhaps db.h has some problem with defining _XOPEN_SOURCE_EXTENDED (or

a file that implements the specific features you want.

I removed the definition of _XOPEN_SOURCE_EXTENDED from the project file (it
ends up in configure, apparently, and is defined on the command line for
compiling each file) and put it in the file form.c, which calls ncurses. That

It won't work properly for several platforms, since they rely on it being defined from the command-line, to precede all of the header-files. Ditto for _XOPEN_SOURCE, _POSIX_SOURCE, _POSIX_C_SOURCE. That's why I define those in the makefile.

Apparently this define is processed in features.h which defines
__USE_XOPEN_EXTENDED, then math.h looks at __USE_XOPEN, but not
__USE_XOPEN_EXTENDED. I'm not sure what db.h is doing; it must have something
to do with a file included by db.h.
